How to use
With the help of this program at Cubens you can build the graph of the function online.
- decimal fractions you need to divide via point
- in some cases it is possible not to write the multiplication signs
- you can build a variety of graphs of functions simultaneously
- you can customize the names and intervals of the axes
- graph can be downloaded as PNG image
- graph can be printed
- you can obtain a link to the graph to share it with others
- when the cursor is on the graph you can move it and increase or decrease the scale

Modes
Currently, the program provides four modes:
- Simple — in this mode, you can draw graphs of functions defined by the equation
- Parametric — allows you to plot curves given parametrically, i.e., in the form of
- Polar coordinates — allows you to plot curves given in polar coordinates, the equation
, where 
is the radial coordinate and the 
is the polar coordinate - Points — this mode is intended for plotting functions specifying the coordinates of their points
, where 
is the radial coordinate and the 
is the polar coordinateThe graph of the function
Dependency variable 
of variable 
is called a function if to each value of corresponds to a single value of .
The function is denoted by a single letter 
, 
or 
.
The domain of the function is all values that can take an argument (variable ).
The value of the function is all values that a function can take (variable ) for all from the field definition of the function.
The function can be set using the table, graph, or formula. The formula specifies a rule that each value of argument is assigned the value of the function .
The graph of the function is the set of all points in the coordinate plane with coordinates 
, where the first coordinate of runs all scope of options of , and the second coordinate is the corresponding value function at the point .
